Gearbox protocol

This repository contains the smart contracts source code for Gearbox Protocol V1.

What is Gearbox protocol?

Gearbox is a generalized leverage protocol: it allows you to take leverage in one place and then use it across various DeFi protocols and platforms in a composable way. The protocol has two sides to it: passive liquidity providers who earn higher APY by providing liquidity; active traders, farmers, or even other protocols who can borrow those assets to trade or farm with x4+ leverage.

Gearbox protocol is Marketmake ETHGlobal hackathon finalist.
